which geometric series converges?
Answer:
Option (1)
Step-by-step explanation:
In a geometric series,
[tex]\sum_{n=0}^{\infty}ar^n=a+ar^1+ar^2+....[/tex]
Here r = [tex]\frac{a_n}{a_{n-1}}[/tex]
For |r| < 1, series will converge.
For |r| > 1, series will diverge.
Option (1)
Given geometric series is,
[tex]\frac{1}{2}+\frac{1}{4}+ \frac{1}{8}+ \frac{1}{16}.......[/tex]
Common ratio = [tex]\frac{\frac{1}{4}}{\frac{1}{2} }[/tex]
= [tex]\frac{1}{2}[/tex]
Since, [tex]\frac{1}{2}<1[/tex]
Series will converge.
Option (2)
[tex]\frac{1}{2}+1+2+4+......[/tex]
r = [tex]\frac{1}{\frac{1}{2}}=2[/tex]
Since, 2 > 1,
Series will diverge.
Option (3)
[tex]\frac{1}{2}+ \frac{3}{2}+ \frac{9}{2}+ \frac{27}{2}+......[/tex]
Common ratio 'r' = [tex]\frac{\frac{3}{2} }{\frac{1}{2} }=3[/tex]
Since, 3 > 1,
Series will diverge.
Option (4)
[tex]\frac{1}{2}+3+18+108+.....[/tex]
Common ratio 'r' = [tex]\frac{3}{\frac{1}{2}}=6[/tex]
Since, 6 > 1
Series will diverge.
Therefore, Option (1) will be the correct option.
1. One week a student exercised 3 hours at school and 1/4 hour at home. If 1/4 of the student's total exercise came from playing basketball, how much time did the student spend playing basketball that week?
2. One week a student exercised 2 hours at school and 1/4 hour at home. If 1/4 of the student's total exercise came from playing soccer, how much time did the student spend playing soccer that week?
Answer:
1- The student spent 48 minutes and 45 seconds playing basketball.
2- The student spent 33 minutes and 45 seconds playing soccer.
Step-by-step explanation:
1- If during a week the student exercised for 3 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 195 minutes (60 x 3 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 48 minutes and 45 seconds playing that sport (195/4).
2- If during a week the student exercised for 2 hours at school, and for 1/4 hour at home, it could be said that the student exercised for a total of 135 minutes (60 x 2 + 60/4) . Now, if I exercise 1/4 of that time playing basketball, the student spent 33 minutes and 45 seconds playing soccer (135/4).

Find the missing measures. Write your numerical answers only with a comma in between.
Answer:
m∠T = 72°
m∠U = 54°
Step-by-step explanation:
Property of an isosceles triangle,
Opposite angles of two equal sides of an isosceles triangle are equal in measure.
By this property, in the given triangle STU,
Since, ST ≅ TU,
m∠S = m∠U = 54°
Since, sum of interior angles of a triangle is 180°
m∠T + m∠S + m∠U = 180°
m∠T + 54° + 54° = 180°
m∠T = 180° - 108°
m∠T = 72°

Mrs. Hopkins made four different pies for Thanksgiving dinner at her house. Each pie was the same size.
She cut the blueberry pie into 6 equal slices, the apple pie into 5 equal slices, the peach pie into 3 equal
slices, and the chocolate pie into 4 equal slices.
Her grandchildren. Alyssa, Bobby, Caitlin, and Dylan, each had one slice of pie but only ate a portion of
that slice. Each grandchild chose a different kind of pie.
Alyssa had the largest slice available and ate 1/4 of it
Bobby had the smallest slice available and ate 3/4 of it.
(The slice Caitlin had was larger than the slice Dylan had.)
Caitlin ate 1/2 of her slice.
• Dylan ate 2/3 of his slice.
What kind of pie did each person choose? And what fraction of the total pie did each person eat?

The point (3, y) lies on the line y = 4x + 5. Find the value of y.
Answer:
y = 17
Step-by-step explanation:
y = 4x + 5
since the x value is 3 you substitute it in
y = 4(3) +5
y = 12 +5
y = 17

Total ounces=11
1st recipe=6 ounces
2nd recipe=1/4 ounces
1 pound =16 ounces

= 4 ounces
First recipe + Second recipe
= 6 ounces + 4 ounces
= 10 ounces.
10 ounces of walnuts and Marni has 11

An artist sculpted a scale model of a giraffe for the zoo gift shop. The artist used the scale 1 inch: 4 feet to create the scale model giraffe. The actual giraffe at the zoo is 20 feet tall.
How tall is the scale model giraffe in inches?
Enter your answer in the box.
inches
Answer:
The scale model giraffe is 5 inches tall.
Step-by-step explanation:
Since the artist sculpted the figure of the giraffe with a scale of 1 inch = 4 feet, and that the real giraffe that lives in the zoo is about 20 feet, to determine the size of the sculpted giraffe to scale it is necessary to perform the following calculation:
20/4 = X
5 = X
Thus, the scale sculpted giraffe that will be sold in the gift shop measures 5 inches.

Find the time it takes for a rocket following the path, h(x) = - 3x2 + 18x, to reach a maximum. In your final answer, include all of your calculations and a verbal explanation of the process that you followed in your solution.
Answer:
it takes 3 seconds for it to get the the maximum height
Step-by-step explanation:
well this is easy bc it is negative so we know it goes down, meaning the vertex will be at the top/highest point.
so all u gotta do is find the vertex which is x=-b/2a
now we gotta plug the numbers in and solve
h(x)=-3x^2+18x
x=-18/2(-3)=-18/-6=3
voilà there is the answer, 3 seconds

What is the rate of change ? Please help!
Answer:
It is 1000
Step-by-step explanation:
To find the unit rate, we divide y/x. In this case our y is the height (ft) and the x is the time(min).
If we divide 1000/1, we get 1000
If we divide 2000/2, we get 1000
and so on...
